ATSSS01-Telex Interface
ATS - SS01 UNIVERSAL TTY TELEX INTERFACE
The ATS-SS01 is a telex interface box that enables a computer to be connected to public or private telex networks. Connected to a printer may be used as a receive-only telex.
Features
- 2W - 4W operation
- Type A / B signaling
- Answerback in EEPROM
- Integrated line bypass switch
- 50 - 300 baud operation (private line)
- Incoming message buffer
- Manual and Automatic signaling functions
- Approved line interface components
- Highly efficient power supply
Application
The ATS-SS01 Universal Teletype - Telex Interface is suitable for connecting a host computer to the public switched telex network or for point-to-point teletype connections. The interface automatically translates ITA-5 (National - ASCII) codes to ITA-2 (Baudot - Murray) codes and vice - versa.
Interface options are easily selectable via connector and jumper changes. The interface may be set for 2-wire or 4-wire operation. Connection to the telex line is done via modular type receptacle.
Communications to and from the host computer are echoed to the built-in printer port, making the ATS-SS01 suitable for receive-only teletypewriter applications, with the addition of an optional printer.
Front panel indicators display the status of both the host computer and telex line interfaces. A resettable audible alarm will notify the operator in case of line problems.
The ATS-SS01 features a wide-range mains power supply which accomodates virtually any available type of AC power and may withstand severe brown-outs.
Software
The ATS-SS01 includes control software for plain telex operation. In addition, the communications protocol is provided, enabling the development of custom applications and integration of the unit in existing communication systems.Optional text message handling packages may be used for specialised applications (ICAO AFTN, NATO ACP-127 etc.)
Custom Applications
The ATS-SS01 may be customised to meet specific customer requirements.
